The
assembled and tested PCB that evaluates the
MAX17435 IC. The MAX17435 is a multichemistry battery
charger controller with SMBusK programmable charge
current, charge voltage, input-current limit, relearn
voltage, and digital readback of the IINP voltage. The EV
kit is capable of supplying power to a system load while
simultaneously charging multichemistry battery packs.
During operation, the EV kit circuit automatically selects
the AC adapter input or the battery as the main power
source for supplying power to the system load. Whenever
the EV kit current limit is exceeded, the battery-charge
current is reduced automatically to give priority to the
system load.
The
voltage, and maximum battery-charge current can be
programmed through the SMBus-compatible serial
interface, communicating at data rates up to 100kbps.
The SMBus data is sent through an on-board USB
interface circuit using a PC or a user-supplied SMBus
controller.
The EV kit also features Windows
XP
provides a user interface for exercising the MAX17435’s
features. The program is menu driven and offers a
graphical user interface (GUI) complete with buttons and
checkboxes.
